IMPROVEMENT IN OPERATING THE 'PICKER-STAFF QF LOOMS.

The Schedule referred to in these Letters Patent and vmak-ing part of tne same.

I I, WANTON ROUSE, of llaunton, in the county of Bristol and State of Massachusetts, have invented certain Improvements in Picker-staff Motions for Looms, of whichA the following is aspecilieation.

The first part. of my invention relates to the combination of a connecting-arm, lying on one side of the rocker, with the rocker and bed, and a stop, so arranged that the stop will, when the mechanismi's combination of the journals with their. openA boxes, so

that the journals and their open boxes will be locked together when the mechanism is ready for use.

In the drawing- Figures 4 and 5 are views of a picker-stati' mech anism embodying my invention, and the otherfigures represent various modifications of the same.

In figs. 4 and 5 the connecting-arms A A have each a journal, B B, upon each end, which journals enter boxes, 011e in the rocker and the other in the bed, thus connecting the rocker with the bed.

There is a small slot, a, in each arm, so formedv in relation to the stops l) that', when-the arms are in place, and the-rocker rests upon the bed, the stops are within the slots; but when -the rocker is lifted from the bed, as in fig. 5', these stops become disengaged from the slots.

These stops operate to prevent any sidewise movement of the arm away from the rocker when the rocker is in place upon .the hed, but are so arranged in relation to the arm that, when it is raised with the rocker, as shown in fig'.'5, the arm can bcmoved sidewise to and from the rocker, thus allowing the journals to be inserted endwise in their boxes, or the boxes to beput onto thejournals in the same manner.

ln figs. 4 and 5 the journals-atl the bed end of the arms are shown in open boxes, and these journals are locked in these boxes by means of a shoulder, y,

the open box through the opening, while, at the same time, they can be readily inserted in and removed from their open boxes through the opening, by bringing the parts in such lrelation that thc shoulder'does not prevent it.

These figures also show a third subordinate feature of my invention, namely, a divided link for the purpose of connecting the rocker and the bedL They also'show 'a fourth subordinate feature, namely, maliingthe arm 'of such a shape that it will ot' itself operate as a shoulder to lock the journals in their open boxes. These shoulders are marked X X.

flhe principle of the rst part of my invention consists in having some portion ofthe connecting-armin such relation to a stop that, when the'rockerand arm are inV place ready for operation, aportionof the arm will lie between the rocker and the stop; and -so arranging the rocker and stopV relatively to each other that the arm cannot move sidewise Iaway from the rocker until the stop is out of the way.

It is obvious that this principle may be applied to a great number of modifications of the mechanism shown in figs. 4 and 5.

j lLhus I have contemplated the application of this principle as shown in Figures 1 and 2, where apportion of the connecting-arm lies between the ear or horn c,

which projects upward fronleach side of the bed and the rocker for these ears or horns may be formed upon the rocker and project downward in such manner that the connecting-arm lies between these `ears or horns and the rocker.

Also, as shown in Figures 1() and l1, when the outer wall of the slotaforms the stop, and an'y ear, b, which is a portion of the connecting-arm, lies -between that wall ot' the slot 'a and the bed and rocker.

Also, as shown in-Figures 8 and 9, when the stop forms a part of the journal-box, and a portion of the connecting-arm, the lin c liesbetween it and the rocker. When this latter mechanism is put together, -the iin c passes sidewise through a slot in the box, until the journal is inpla'ce, and the arm is then turned upon' 'the journal as a center, which causes the fin c to enter a slot in the box at right angles to the first slot, thus locking the arm, as already explained.

It is obvious that this part ot' my invention is not confined t-o connecting-arms bearing journals, nbut mayl lequally well be applied to such arms bearing boxes,

as will be plain from Figures 3 and 12, both of which show connecting-arms A bearing boxes instead of journals, but held in placeeprecisely as the arms in the other figures showing this part of my invention.v f I am aware that a connecting-arm has beeninserted.

within a long slotn the rocker and in the bed, as in `Letters Patent granted to Wright, October 29, 1867,

and to Rollins, Marcli 11,1862; also that the 'jour,`v

nais have been rconnected together' by an arm from each cud, thus forming a'four-sided link, as in Letters for use, the rocker, or the bed, or both, acting as a stop; but in none of these mechanisms is it possible to insert the journals in their boxes endwise, but in all the journals are laid in their boxes sidewis'e, which is obvious from the fact that open boxes must necessarily be used in all these mechanisms, while in my mechanism this is a matter 'of choice, as the stop is so arranged with regard to the arm and rocker that the journal can always be inserted in or drawn from the box, while its axis is coincident with the axis of the box when the rocker is lifted from its place.

I disclaim, therefore, all the devices and combinations Shown in any of said Letters Patent, as the principle ot this part of my invention, as before explained, relates only to preventing the endwise motion of the journals in their boxes while the mechanism is in use, Vand at the same time allowing this cudwise motion when the rocker is raised from its'bed, .as above described.

The principle of the second part of my invention consists in using a shoulder in such relation to the journal that a portion of the wall of the open jour- .-nal-box will lie between the shoulder and journal, s o

that the journal will be prevented from escaping through the opening of the box when the mechanism is in use.

It is also obvious that this principle may be applied in various modified forms of' mechanism. Figures 6 and 7, the shoulder is produced by the shape of the connecting-arm, and in tig. 3 the shoulders are formed, one upon the rocker, and the other upon the bed, as the boxes are upon the conuecting-arm.

A single/arm may be used, as shown in figs. l0, 11, and12, but I prefer to use `two arms.

Open boxers, though they have many advantages, are

liable to serious objections,and the rst part of my iuvention is intended more especially 'for motions wherel the boxes are closed.- When both boxes are open, the irst'partof my invention is of secondary importance, as thearms may -be'connected by the journals,

.making a common form of motion, in which the rocker and bed are connected bya link, the inside lines of which form a parallelogram.`

Fig. 7 shows this link, but made in accordance with the second part of my invention.

The twoeonnecting-arms, also, which compose this link, 4are each made with shoulders, lying parallel with the journal of theiink, said shoulders being marked Thus, in'

:e 1', and each in accordance with the fourth part of my invention.A

The third part of my invention, the divided llink, may be used without the irst or second parts of my invention, as the parts of the link may be prevented from sidewise movement away from the rocker by other means than those shown for instance, a wire may be passed through the journals, and riveted, as shown in Figure 13, or thel two arms may be secured together after they are in place, in any other suitable manner.

Heretofore the width of the rocker and of the bed deter-mined the length of the journal-boxes in all motions in which the rocker and bed were connected together, either by one or two arms, from the ends of which journals projected, and, as it is important to make both the rocker and the bed quite narrow, -these boxes are never long enough to'give a-sufficient bearing. To remedy this diiculty I construct my rocker and bed with the journal-boxes projecting, and am thereby enabled to securevas long a bearing as may be desired without making the rocker or thc bed too bulky.

I do not claim combining the rocker and bed by means of an arm or arms, nor do `I claim combining them by means of a link.
